    Aerodynamic design of buses inspired by sperm whale
    (International Conference on Computational Fluid Dynamics 2016, 2016) Arabacı S.K.; Pakdemirli M.
    In this work, drag forces and drag coefficients of various bus models are investigated in CFD and wind tunnel. Reduced drag forces result in lower fuel consumptions. For new designs of buses, inspiration is taken from nature. Sperm whale shape forms are used in the analysis. The buses are drawn using UNIGRAPHICS program. The drawings are inserted into ANSYS CFD program for meshing. Drag forces and drag coefficients corresponding to the various designs are determined using Fluent (solver) and CFX (result) program. To compare with the experimental results, the experiments are carried out in a wind tunnel. Test data and CFD results are compared. Substantial reduction in drag coefficients is possible for these new geometries which are inspired from whales. © 2016 9th International Conference on Computational Fluid Dynamics, ICCFD 2016 - Proceedings.
